Welcome to the Virus Encyclopedia of Panda Security.
It allows to gain remote access to the affected computer. It spreads and affects other computers.

|Sdbot.LEZ is a worm with that has backdoor characteristics. Sdbot.LEZ spreads by copying itself, without infecting other files. Its main objective is to collapse computers and networks, thus preventing users from working on their computers.|
Furthermore, due to its backdoor characteristics, Sdbot.LEZ allows hackers to gain remote access to the affected computer. Therefore, hackers will be able to carry out actions that compromise user confidentiality and impede the tasks carried out on the computer.
It affects productivity, preventing tasks from being carried out:
- In the affected computer:
causes system slowdowns.
- In the local network:
it generates a large amount of network activity and consumes bandwidth.
It reduces the security level of the computer:
it terminates processes belonging to security tools, such as antivirus programs and firewalls, leaving the computer defenseless against attacks from other malware; it awaits remote-control orders received through
It uses stealth techniques to avoid being detected by the user:
- It terminates processes corresponding to several security tools, such as antivirus programs and firewalls, to prevent detection.
- It injects itself in running processes.
- It deletes the original file from which it was run once it is installed on the computer.
Sdbot.LEZ uses the following propagation or distribution methods:
- Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.
- Computer networks (mapped drives): it creates copies of itself in mapped drives.
- Computer networks (shared resources): it creates copies of itself in shared network resources to which it has access.
